FEVER DISASSEMBLE PIPE OF VARIABLE PITCH TYPE AND OIL EXTRACTION APPARATUS USING THE SAME

摘要

The present invention relates to an apparatus for extracting oil from waste plastics and, more specifically, to a variable pitch type pyrolysis pipe and an oil extractor using the same capable of gradually decreasing the pitch of a transfer screw for transferring a raw material such as waste plastics. Therefore, the transfer of the raw material can be facilitated even when the volume of the raw material is decreased due to liquefaction.
